Knights Of Badassdom follows three best friends (Dinklage, Kwanten, and Steve Zahn) and dedicated LARPers (Live Action Role Players) as they take to the woods to reenact a dungeons and dragons-like scenario fresh out of the mythical Middle Ages. Trouble arises after they unwittingly conjure up some serious evil in the form of a blood-lusting Succubus, from the pits of hell.
